The Additive Pulmonary Vasodilatory Effects of Inhaled Prostacyclin and Inhaled Milrinone in Postcardiac Surgical Patients with Pulmonary Hypertension

Abstract

Pulmonary hypertension may cause or aggravate right heart failure. IV vasodilators reduce systemic blood pressure and might thereby further impair coronary perfusion and right heart performance. In the present study of cardiac surgical patients with pulmonary hypertension, selective pulmonary vasodilation without systemic effects was induced by nebulized, inhaled vasodilators.
